Frangible copper projectile.
This projectile was described as nearly pure copper with a bit of nylon to hold it together. "Frangible" means it's designed to fragment into thousands of little pieces on impact. This serves two purposes: Increasing damage to the target (i.e. makes a bigger hole) and limiting the danger of the projectile bouncing around in an enclosed space and hitting the shooter.Source:Derek McKinleyContributor:Derek McKinleyAcquired:6 April, 2007Text Updated:6 April, 2007Price: DonatedSize: 0.5"Purity: >90%
